Panted Mar. 14, 1911.

Continuation of application Serial No. 388,430, filed August 13, 1907.This application led February 17,

.To all whom 'it may concern:

Be it known that I, AUGUST WAGNIERE, a citizen. of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Loose-Leaf Binder, of whichthe following is a specification.

An object of this invention is to provide an improved loose .leaf binderin which the binder may be filled -with blank leaves and the leavesconveniently removed for typewriting from. time to time and replaceduntill the record is complete, and then the book may be permanentlylocked so that it cannot be unlocked without breaking.

The loose leaf binder herein described embraces the features shown in myapplication for loose leaf binder for record books, filed August .13,1907, Serial No. 388,430, and of which application this is a continuance with relation to the patentable features of said formerapplication.

The accompanying' drawings illustrate the invention.

Figure 1 is a perspective showing a book constructed inaccordance withthe principles. of my invention, the binder-posts being dis connected attheir back ends so as to allow the removal or replacement of .the backsheets ofthe book. Fig. 2 is a View analogous to Fig'. l and showing thebook open for the removal or replacement of the front sheets. aFig. 3`is an enlarged cross-section on line m3, Fig. 6 and showing thechannel: back rectangular in cross-section. Fig. 4 is a view analogousto Fig. 3 and showing the channel-back curved in cross-section Fig. 5 isa view analogous to Fig. 3 and taken on line :125, Fig. 6; the bookbeing closed. Fig. 6 isa plan of the parte shown in Figs. 3 and .5,parts being' broken away to economize space, and parts bein shown insection to illustrate the construction. Fig. 7 is a longitudinalvertical section on line m7, Figs. 3 and 6 and illustrating the use ofthe stop to prevent the permanent locking of the binder-posts, andshowing the parts temporarily latched. Fig. l8 is a View analogous toFig. 7 and showing the 'parts unlatched.

Fi 9 is a view analogous to' Figs; 7 and 8 an showing the stop removedand the parts permanently locked.y Fi tion showing a straightinder-post. Fig. l1 is an elevation showing a curved binder- 10 is aneleva? post. Fig. 12 is a sectional detail of a set of binder-posts andthe locking-bar, drawn for the purpose of illustrating the pro ressiveaction of the locking lingers, the arthest entering the opening in thepost first, then the middle finger, and then the nearest finger. Fig. 13is an enlarged fragmental sectional detail showing the construction ofthe fly-leaf. Fig. 14 is a cross-sectional detail of a modifiedconstruction.

Referring to the drawing in detail., the frame-Work l of thechannel-back comprises the central portion 2 and the side portions 3 and4 formedofsheet metal and producing a channel which is rect-angular incrosssection as shown in Fig. 3, or curved' as shown in Figs. 4 and 14.l

The locking. bar mechanisms 5 are secured one to the side portion 3 andanother to the side portion 4, or as shown in Fig, 14 only one lockingbar mechanism may be used. Each locking bar mechanism comprises 'acasing G, a. slide 7, anda loclcmechanism 8. The casing @comprises thefacing 9, the` flange 10 extending from the lower edge of the facing,the flange 11 extending fromthe upper edge of the facing parallel withthe flange 10, and the flange'lQ extending from the flange 11 parallelwith the facing 9; there being spacin" 'bearing blocks 13 cut andpressed from tie body of the facing 9 at intervals, and rivets 14inserted through the spacing bearing blocks and through the sideportions 8 and 4 to hold the locking bar mechanisms in place.;

The inner binder-ilaps 15 and 16 are placed against the inner faces ofthe side portions o and 4 beforefthe locking-bar mechanisms are placed'1n position, so that by attaching the locking-bar mechanisms thebinder-flaps lare held.

Notches 17 are cut in the upper edges of the casing 6 to receivethe-ends of the binderposts. The slides 7 are mounted in the casing 6before the casings are secured-in position, each of said slidescomprising a piece of the metal 18 of the desired length and of a widthand thickness to fit and slide readily in its casin the near end of themetal beingbent latera ly and suitably finished to form the handle 19for moving the slide back and forth, and there being bearings 20punched.

at suitable intervals to lit. the spacing bearing blocks 13, and therebeing notches lQ1 posts, and there being elongated"4 punched atsuitableintervals to match'ftheY posts will straighten up so that theperfora- .tions in the tree ends of the posts will be in notches 17 toreceive the endsl of the 'binderas iingers22 projecting toward temnothes to enter the perforations in thebinder-posts.

The removable stop.23 consists of a screwv screw-seated in the metal 18just inside of rejections the handle 19 to engage the end of the icasingand limit the inward movement of the slide, so that while the'istop isin place the back can only be temporarily latched or locked as requiredto remove and replace the leaves.

The locking-bar mechanisms 5 may be flat or rectangularl incross-section, shownin F ig. 3, or they may be curved as shown in Fig.4. Each locking-bar mechanism contains a concealed lock -in'echanism 8.comprising a spring detent 24 mounted in a slot .25

formed in the metal- 18, the tree end of the spring' operating in anotch 26 in the metal 18, and the stop 25 extending downwardly from theflange 11 intothe casing so that when the partsare assembled the springdetent Q4 is depressed and slides against the end of the stop 25 whilethe removable stop 23 is in place, so that the slide 7 may be movedbackwardly and forwardly as desired to latch and unlatch thebinder-posts, and so that when the removable stop 23 is removed and theslide pushed into the casing far enough the free end of, the springdetent 24 will pass beyond thestop 25 and spring up behind the stop, andthen the slide is perH manently locked and cannot be unlocked oroperated except by breaking some of the parts, there being no Vaccess tothe spring detent 24 either by key or otherwise,

In laying ofi' the locking bar mechanisms the partsmay be soproportioned that the fingers 22 will 'all' enter perforations in thebinder-posts simultaneously, or the parts may beso arranged that thelingers will enter the perforations successively, so that a finger maybe started into one post, and then started in to the next, andthen intothe next,

as illustrated inFigs. 7 and 12.7`

The-binder-posts 27 each comprises a section 28 of rod, preferably roundin cross section and having perforations 29 in each end, and the endface 30 adjacent the perforation being preferably concentric to theperforationand the forward end 31 of eachperforation being enlarged orfunnel-shaped.

. The binder-posts may be straight pins, as shown 1n Fig. 10, or theymay be curved `pins as shown in Fig. 11. The points of the Pfingers orprojections -22' are preferably rounded or tapered sc as to find theirwa);

easilyinto the Haring ends 231 ot the perfo- 'ra'ltions`29, and saidlingers are preferably ot' the relative size and shape that will causethe binder-posts 28 lto straighten as the tingers are pressed well intothe posts; itbeing desirable that when theposts are placed in thenotches 17 and the slide. is operated to cause the lingers to enter theposts, the

line. parallel with. the fingers. Then when a. stock of paper 3B formingthe book-leaves previously perforated', is placed upon the posts anmanipulated to bring the paper into the channel 34 of the back` the ree-ends of the Aposts will pass down into :the

notches 17 with their perforatioi'is in line to receive the fingers 22of the slide. rlhe stock of paper is composed of loose flat sheets, eachsheet being free to be removed, tor nstance, to take a blank sheetfrom'the front, typewrite the sheet and place it in the back. Thetlyleaf coi'istruction 35 comprises the back portion, the hinge portionsSi and 38, the eye-portions and 40, the hinge por tions 41 and 42, andthe leaf portions 43 and 44. The back portion is preferably two piecesof cloth i-5 and 4G with a reinforcef ment 4T pastedV between the piecesso as to make the bach section very firm, and said. back section is ot awidth slightly less than the double capacity of the c :hannel 34. Thehinge portions 3'? and 38 are formed by past-- ing the clotli-piecestogether witlwut the reintorcen'ient, and the eye-portions 39 and 40 areformed by placing a reintorcement48 be.-

tween the cloth-pieces, and the eyes 49 are i Sli are formed by bringingthe elo't-hse.ctions to gether as in the hinge-portions 37 and 38,

and then the leatportions 43 and 44 areV formed by insert-ing the leaves50 between .theedges of the cloth-pieces; the object ot this fly-leafconstruction being to produce a suitable and convenientv covering forthe bunch oit book-leaves.

In assembling the parte thus constructed. the cover is opened as inFig. 1. with the 'channel of the back in a. vertical position;

the binder-posts 28 are `placed in the notches 17 ot' the front lockingbar mechanism; the, slide is manipulated to latch ,the binderposts inplace:. the fly leaf construction is Iopened and placed with the leaf 43down- \\ardly`npon thefront coyerwith the binder- `posts extei'idingthrough "the eye-portion 39.

Then the paper 35i is placed upon the bin'derfposts until the posts aretilled to the desired extent; then the back leaf 440i' the flyleatconstruction is pulled tightly over into place. the paper being presseddownwardly iipon the'binder-posts, and the eyeportion 40 is brought intoplace upon the rear ends of the binder-posts with the posts extending'through the eyes,'thereby holding the paper {irmlytogether ina bunch.*.Then .by graspM ino the front cover of the book or thefhlo'clr ofpaper and swinging it upwardly, -thc hinge portion 38 ofthe fly-leafconstruction will strike the upper edge of the'casing 9 and slidedownwardly into the channel 34,

as shown in Fig. 3, and the back ends of the binder-posts will passdownwardly into the notches 17, said posts being held in line to'receive the fingers, and the handle 19 is maplaced against thebinder-Hap and secured ,in place by screws 53 inserted downwardlythrough the framework into the wood. Pads 54 and 55 are placed againstthe sides 3 and 4 of the frame-work outside of Vthe flap 51, and theouter cover 56 is pasted upon the pads 52, 54 and 55 and then to theflaps 51 and the flaps 51 to the ilaps 15 and 16 to form the hingeportions'57 and '58 oi the cover, and the boards 59 and 60 are placedbetween the flaps 5l and the flaps 15 and 16, and the cover is completedin the usual way.

In F ig. 14 I have shown a crossf section of a book-binder like thatshown inmy Patent No. 842,361, dated January 29, 1907, and in thisconstruction the binder-posts 61 are secured to a bar 62 which isconnected by a hinge 63 to the channel-back 64E, and perfo rations 65are-formed in the free ends of the binder-posts 61 to receive thefingers 22 of the slide; the diierence between this construction and theconstruction shown in my former patent being that the lingers passthrough perforations in the binder-posts,

whereas in my former patent 'the fingers pass over the binderosts;

In Fig. 5 I have s own the ily-leaf construction in two parts, the lineof .division being substantially at the center of the back 36, but inthis construction theiiy-leaf does not serve the purpose-of binding thepaper together. into a block as in the construction heretofore describedand shown in Fig. 3.

It is obvious that after the paper has been bound into a block as shownin F.' 3, the front slide may be operatedl to release'the binder-postsand the block of paper held together by the fly-leaf construction, and.the binder-posts' could be manipulated independently of the binder orcover.

The fingers or elongated projections 22 may be cylindrical as thepreferable form of pivotdor the binder posts-or pins.

I claim i 1I In a loose leaf binder, the combination with a' bundle ofloose leaves, of a fly leaf construction vcomprising' two leaves eachprovided with eyes, binder posts inserted 60 through the eyes of bothleaves, a back, and means outside the {1y-leaves to ivotally anddetachably fasten both ends ci] each 4binder post tothe back.

y 2. In a loose leaf binder, the combination with two leaves and aehannelshaped back,` of a casing at each side of said back, the u peredge of each casing beingsubstantia y `even with the side `-of saidchannel and notched at intervals, a longitudinallymov` able slidemounted in each casing with its upper edge provided with elongatedprojectons adapted to be moved into and out' of register with saidnotches', and a plural ity of straight, reversible pins adapted t0extend across said channel, each with its ends in the opposite notchesof said casings, each end being perforated through-which perforationsthe projections on the slides are adapted to be moved back and forth t0lock the pins against movement or to permit eitherend of each pin to bemoved-upward away from said channel when said end has been released bythe withdrawal of the pro- -jections of the slide upon that side and theprojections upon the other slide are within their respectiveperforations and are acting a'sdpivots for the ends of the pins uponthat s1 e.

8.' In a loose leaf binder, the combination with: a substantiallyrectangular channelshaped back and two cover-leaves hin ed to the upperedges thereof, an open-si ed, fiat' casing secured to each side oftheback with its' upper edge substantially even with 9. the top of saidside and recessed, the recesses of the two casings being opposite eachother, a slide in each casing'havingits upper provided with cylindricalprojections, eac adapted to bemoved longitudinally S0 as t0 span one ofsaid recesses" or to be'withdrawn t-herefrom,'and a plurality ofstraight' pins removably mounted in said opposingirle- 4cesses so as toextend .from side to side ofthe back, each end of each pin beingperforatd-1qg' forthe reception of one of said projections," f' wherebyeither endof each pin may be re. leased so as. to be removed fromVitsjrecefs'sjwhile the'other end remains secured and-.5Fl acts as apivot. 11

In testimony whereof- I` -have hereunto v set my hand atiLos Angeles,California, 10th day of February, 1909.
